+# Fusion baselines
+
+Per-device baselines for `test-fusion`, one CSV per backend (e.g. `MTL.csv`). Rows are
+`arch,moe,mode,label,count`. Regenerate a CSV whenever fusion patterns change.
+
+## Update a baseline
+
+```sh
+cmake -B build -DCMAKE_BUILD_TYPE=Release -DGGML_METAL=ON   # enable the target backend
+cmake --build build --config Release --target test-llama-archs --target test-fusion -j
+
+rm -rf build-ci-models && mkdir -p build-ci-models
+./build/bin/test-llama-archs -o build-ci-models
+
+./build/bin/test-fusion --models build-ci-models --device MTL0 --record MTL.csv
+```
+
+## Validate
+
+```sh
+./build/bin/test-fusion --models build-ci-models --device MTL0 --check MTL.csv
+```
+
+Non-zero exit means a row differs from the baseline. Use `--model FILE` to run a single
+architecture. `--check` also reports baseline rows that the run no longer produces, so a fusion
+that stops matching fails the run instead of silently dropping out of the CSV.
